Systems and methods for continuous measurement of an analyte in a host are provided. The system generally includes a continuous analyte sensor configured to continuously measure a concentration of analyte in a host and a sensor electronics module physically connected to the continuous analyte sensor during sensor use, wherein the sensor electronics module is further configured to directly wirelessly communicate sensor information to one or more display devices. Establishment of communication between devices can involve using a unique identifier associated with the sensor electronics module to authenticate communication. Times tracked at the sensor electronics module and the display module can be at different resolutions, and the different resolutions can be translated to facilitate communication. In addition, the frequency of establishing communication channels between the sensor electronics module and the display devices can vary depending upon whether reference calibration information is being updated.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, further comprising: upon receiving the first encrypted message, generating a second encrypted message using at least the first parameter in the first encrypted message and an encryption method used to generate the first encryption message.
3. The method of claim 2, wherein the verifying further includes comparing the first encrypted message with the second encrypted message.
4. The method of claim 2, wherein the determination of the status further includes indicating a valid status of the authentication protocol when the second encrypted message matches with the first encrypted message.
5. The method of claim 1, wherein the authentication protocol is executed at an application layer.
7. The system of claim 6, wherein the instructions, when executed by the one or more processors of the system, cause the system to, upon receiving the first encrypted message, generate a second encrypted message using at least the first parameter in the first encrypted message and an encryption method used to generate the first encryption message.
8. The system of claim 7, wherein the instructions, when executed by the one or more processors of the system, cause the system to compare the first encrypted message with the second encrypted message for the verification.
9. The system of claim 7, wherein the instructions, when executed by the one or more processors of the system, cause the system to indicate a valid status of the authentication protocol when the second encrypted message matches with the first encrypted message.
10. The system of claim 6, wherein the instructions, when executed by the one or more processors of the system, cause the system to execute the authentication protocol at an application layer of the system.
